2 wet/dry filter will do the works on it. just get something like for a 300 gal capacity each and a large pump for both of them. you don't really need 2 pumps one nice and reliable powerful pump with do the trick. saving money doesn't mean your not going to have a good filter it only means you're thinking wisely and investing properly on a long term hobby that wouldn't end up hurting your pocket in the long run.
